Abstract: PURPOSE:To improve the accuracy of reading by providing a means to prohibit the time axis correction operation of a time axis correction circuit only at the specified section where digital data is overlapped. CONSTITUTION:When the overlapped video signal of a teletext data D is outputted to the 20H and 21H of scanning line in the vertical return line period from a demodulator 1, the 20th signal of horizontal synchronization signals outputted from a synchronization separator 2 is inputted to the clock of a counter 61, the 20H output of a counter 81 and the output of an OR gate 62 are turned to high level.
